#6951 closed defect (wontfix)

grid's horizontal scrolling broken in opera

Reported by: guest Owned by: nathan
Priority: high Milestone:
Component: DojoX Grid Version: 1.1.1
Keywords: opera grid Cc: sidlon@…
Blocked By: Blocking:


Use Opera (either the stable Opera 9.27 or the new rendering engine in 9.50 beta 2) to view the following URLs:

If you scroll a grid horizontally, the header row doesn't change.

I realize Opera isn't officially supported by dojox, but hopefully this won't be too hard to fix. Opera 9.5 seems to be significantly faster than Firefox for displaying many dojo widgets.

This seems to be a problem with opera not allowing us to set scrollLeft on the header node. Immediately after setting it, Opera reports that scrollLeft is always 0.

Marking as wontfix.

I've done some basic testing to verify that Opera 9.27 and 9.50 do support 'scrollLeft' as a read/write property. (see the attachment)

Would it be possible to get more detail on the situation where setting scrollLeft fails? If Opera is doing something strange, I'd love to get a minimal example to give their developers.

Yeah - that's the thing - scrollLeft works just fine in many places - but for some reason, it dies in this case...

In dojox/grid/_View.js, there is a function called "doscroll". In it, there is the following line:

this.headerNode.scrollLeft = this.scrollboxNode.scrollLeft;

Doing a console.debug(this.scrollboxNode.scrollLeft, this.headerNode.scrollLeft); immediately after that shows opera has a scrollLeft value for the scrollboxNode, but the value isn't "sticking" for the headerNode.

All other browsers return the appropriate value. I am unsure of how to distill that into an easier test case for the opera developers...

Setting width of headerNodeContainer to "32766px" (it is max value) instead of "9000em" solves this problem. Seem that Opera doesn't work correctly with higher values (see attachment above).

Solution: Just change




in dojox/grid/_View.js, line 22 (from dojo-release-1.5.0)

I think 32766px is quite enough for grids... as well as 9000em

Definitely marking as wontfix at this point, because we don't truly support Opera (especially 9.x), and because there are other grids that are superceding this work. Thank you for the reports though.
